Answer:
Step-by-step explanation:
<u>Given</u>
<u>This is symmetrical for x and y, so</u>
- y#x = 1/(1/y + 1/x) is same as above
<u>If x#y = 7, then:</u>
- 7 = 1/(1/x + 1/y)
- 1/(1/7) = 1/(1/x + 1/y)
- 1/7 = 1/x + 1/y
<u>Possible value of x is 14, then y = 14 as well:</u>
- 1/7 = 1/14 + 1/14
- 1/7 = 2/14
- 1/7 = 1/7
Correct choice is A
2 * 11/4 * 11/2
step 1. simplify: 2 * 2.75<span> * 5.5</span>
step 2. do the math: <span>2 * 2.75 * 5.5 = 30.25</span>
The answer is 16x because if you add 10 and 2 you get 12 then add 4 you get is 16 but you need to multiply by x so you write it as 16x
Answer
Sorry! number 12 is 2
